Zheng Lu received his Ph.D. from the University of Essex, after which he stayed on to research optical networks and wireless sensor networks. He is experienced in modeling network protocols and he has many years of experience using OPNET Modeler in his research and laboratory demonstrations. Hongji Yang is currently a Professor at the Software Technology Research Laboratory, De Montfort University. He received his Ph.D. from Durham University in 1994 and was a main contributor to the Distributed Computer Networks project sponsored by the Chinese Ministry of Education, from 1982 to 1986.
